A force of 1000 n is exerted on a golf ball for 0. 005 s. The change in momentum of the golf ball is ________.

In amplifiers, the coupling and bypass capacitors appear to be shorts to ac at the mid band frequencies.

At low frequencies the capacitive reactance, XC, of these capacitors affect the gain and phase shift of signals, so they must be taken into account.

\(\alpha =\frac{1}{2\pi f}\)

At lower f, the internal capacitances have a very high Xc like opens and have no effect on the transistor’s performance. However, as the frequency goes up (at high f), the internal  capacitive reactances go down and they have a significant effect on the transistor’s gain and also it introduces a phase shift; it has the inverse effect to the coupling capacitor.

Miller’s theorem states that C effectively appears as a capacitance from input to ground is as given below-

\(Cin= C(A+1)\)

\(Cout=\frac{CA +C}{\alpha }\)

This shows the effective input and output capacitance.

Critical frequency is given as -

The kinetic energy is high because, the mass of the object is large and thus has a great momentum and its velocity low because it has a large mass.

We know that kinetic energy of an object K = 1/2mv² where m = mass of the object and v = velocity of the object and its momentum, p = mv

For a given value of kinetic energy, the mass of the object m = 2K/v². This implies that m ∝ 1/v².

So, as the mass of the object increases, its velocity decreases.

So. an object with large mass has low velocity while an object with small mass has high velocity.

Also, the kinetic energy, K = 1/2mv². So, K ∝ mv². So, if m is large and v is small, the product mv² is large and thus K = 1/2mv² is high.

So, the kinetic energy of heavy vehicles is high because, the mass of the object is large and thus has a great momentum and its velocity low because it has a large mass.

If an object's tangential velocity at closest approach to Earth is less than the circular velocity, it will not have enough speed to maintain a stable orbit. Instead, it will follow a highly elliptical or hyperbolic trajectory, eventually moving away from the Earth.

When an object orbits the Earth, it needs to have a specific velocity known as the circular velocity to counteract the gravitational pull. The circular velocity depends on the mass of the Earth and the object's distance from its center. If the object's tangential velocity at closest approach is less than the circular velocity, it means that the object is not moving fast enough to overcome Earth's gravitational pull.

As a result, the object will follow an elliptical or hyperbolic trajectory rather than a stable orbit. In an elliptical orbit, the object will move away from Earth, reaching its farthest point (apoapsis) before returning to the closest point (periapsis). This path is repeated in a regular cycle.

On the other hand, if the object's velocity is high enough to surpass the escape velocity, it will follow a hyperbolic trajectory, which means it will move away from Earth indefinitely. This occurs when the object's velocity is sufficient to overcome the gravitational pull of the Earth entirely.

In either case, if an object's tangential velocity at closest approach is less than the circular velocity, it will not remain in a stable orbit and will either move along an elliptical path or escape the Earth's gravitational pull.

The rate οf change οf temperature with respect tο time is apprοximately -0.4223 K/min.

Tο find the rate οf change οf temperature (T) with respect tο time (t) at a certain instant, we can use the ideal gas law equatiοn PV = nRT and differentiate it with respect tο time:

PV = nRT

Taking the derivative with respect tο time:

P(dV/dt) + V(dP/dt) = nR(dT/dt)

Since we are interested in finding dT/dt, we can rearrange the equatiοn:

(dT/dt) = (P(dV/dt) + V(dP/dt)) / (nR)

Substituting the given values:

P = 7.0 atm

dV/dt = -0.17 L/min (negative sign indicates a decrease in vοlume)

dP/dt = 0.11 atm/min

n = 10 mοl

R = 0.0621 L·atm/(mοl·K)

(dT/dt) = (7.0 atm * (-0.17 L/min) + 12 L * 0.11 atm/min) / (10 mοl * 0.0621 L·atm/(mοl·K))

Calculating the rate οf change οf temperature:

On Mercury and the Moon, we notice that larger craters overlie smaller craters. This phenomenon occurs because larger impacts create more extensive shockwaves and debris

This observation can be attributed to the geological process known as "crater saturation." Over time, the surfaces of Mercury and the Moon have experienced numerous impacts from meteoroids and other celestial bodies. As a result, smaller craters formed earlier in their history. However, subsequent impacts from larger objects have overlaid these smaller craters, effectively "erasing" them from the surface. This phenomenon occurs because larger impacts create more extensive shockwaves and debris, which can bury or obliterate pre-existing smaller craters. By studying the distribution and characteristics of these overlapping craters, scientists can gain insights into the history and evolution of these planetary bodies.

According to photographs collected by a NASA satellite, the one rocky plate that surrounds Mercury is constricting, twisting the surface into puckered ridges and scallop-edged cliffs known as lobate scarps. This is the first thorough description of the procedure. As Mariner 10 sailed over Mercury, it noticed cliffs and other geological features. These are signs that as the planet's core slowly cools over time, it is compressing, resulting in the crust collapsing in on itself. Mercury's surface landforms imply that its crust may have contracted. They are long, sinuous cliffs called lobate scarps. These scarps seem to be thrust faults, where the crust is broken along an inclined plane and propelled upward.

The puck must rotate with a speed of 3.44 m/s to keep the hanging block at rest.

To keep the hanging block at rest, the tension in the string must be equal to the weight of the block. We can start by finding the tension in the string using the weight of the hanging block:

T = mg = (1.20 kg)(9.81 m/s^2) = 11.77 N

The tension in the string provides the centripetal force that keeps the puck moving in a circle. The centripetal force is given by:

F = ma = m(v^2/r)

where m is the mass of the puck, v is its speed, r is the radius of the circle, and a is the centripetal acceleration.

Solving for v, we get:

v = sqrt(ra) = sqrt(r(T/m)) = sqrt((0.40 m) × (11.77 N)/(0.20 kg)) = 3.44 m/s

Transformer-Rectifier units for CAC-A (Constant Current Arc Welding) should have a minimum of 60% duty cycle, with at least three-phase units.

Constant Current Arc Welding is also known as "stick welding." The acronym CAC stands for "constant current," which means the power source must be able to produce a constant output current, regardless of the resistance of the welding arc.

To create the appropriate current for the welding, a transformer-rectifier is used. A transformer-rectifier unit comprises of a transformer and a rectifier. The transformer converts high voltage, low current AC electricity from the power source to low voltage, high current AC electricity, which is then supplied to the rectifier. The rectifier transforms the AC input into a direct current (DC) output that the welding equipment requires.

The duty cycle is defined as the amount of time during which the machine can operate without overheating. The transformer-rectifier should have a 60% duty cycle or higher because welding generates a lot of heat and needs a lot of power. If the duty cycle is too low, the unit will shut down too often and be unable to perform effectively.

A 60% duty cycle ensures that the welding machine can run continuously for six minutes out of every ten minutes. It is recommended that you choose a transformer-rectifier with a duty cycle that meets your requirements, as a higher duty cycle would allow you to weld for longer periods of time before requiring a cool down period.
